Peace-Full Stones

rox 4 paxWith January fading fast in time’s mirror, Pierre Jardin decided to change the new year’s caption (see previous post) he had made for this display, a stone offering to planetary peace.


Petriverse Welcomes in 2019

Pierre Jardin strives to send positive vibrations into the world, using the beauty of stones and the gift of language. This year he ushered in the new year with two messages.

A wish for peace to envelop the world features the green earth stone from the Yuha desert; here, a slight likeness of a face or skull can be seen, like the man in the moon. Perhaps this betokens the coming of a much-needed, more planet-centered outlook for humanity. In the spirit of caring for the environment, Pierre Jardin offers this message for passersby to consider, as they make their way to shop for groceries at a local store.

Winter Solstice 2018

Held at The Garden of Slow Time at Loyola Marymount University, this Solstice celebration was offered in a spirit of hope for humanity to come together with and on the earth in cooperation rather than competition. The Earth Stone–a hard, shiny green rock from the Yuha desert at the U.S-Mexico border (note symbolic location)–was placed in the center of the labyrinth, where the Solstice Stone casts its shadow at sunset.

This year, the setting sun was graced by the simultaneous rising of an auspicious Cold Full Moon.This conjunction of heavenly bodies was accompanied by world musician Paul Humphreys, who played a beautiful birdsong as labyrinth walkers sent their thoughts into the atmosphere.

Winter Solstice 2018 was a numinous ritual blessed by luminous bodies above and human ones below. We all felt a sweet, shared awe at the beauty of this special occasion, and bring this glowing energy into the holiday season and new year. The light is coming!


Rock Records 0

In celebration of Rock Records, a special issue of SubStance, Pierre Jardin is creating a themed series of installations in The Petriverse.

I heart to play rock record

Jardin loves to ‘play the rock record.’  All work related to the garden is play: collecting rocks at the beach or in the desert, recontextualizing them in the garden, assembling them in compositions, are all guises of “playing rocks.” Compositions are recordings of the rock record; Jardin attempts to “play rocks” for spectators, to make manifest the silent concert of rock groups. He becomes a DJ playing rock records for passersby, making stones POP to the eye and pop-rock for the ear.

Rock Records: Roger Caillois

Caillois holding stoneRoger Caillois’s mineral collection and writings on stone comprise a rich library of ‘rock records,’ a term used here to mean not only the geologic rock record, but also records of encounters with stone broadly understood. Caillois bequeathed his renowned collection to the Muséum national d’Histoire naturelle in Paris. The collection, featured at the 2013 Venice Biennale, can be seen at the galerie de Minéralogie et de Géologie. In his three books on stones, Caillois presents fascinating speculative ruminations on geologic processes and specimens, in the service of a transdisciplinary philosophical project. Caillois espoused a “mystical materialism” that grounded his pursuit of a “diagonal science,” a hermetic reading of the cosmos as composed of hieroglyphic signs, in which “stone… speaks… the most convincing language in the universe.”

Rock Records coverCaillois figures prominently in Rock Records, a special issue of the French theory and literature journal SubStance that includes essays in ecophilosophy and speculative geomedia, and a collection of viewing stones presented by leading connoisseurs. The issue features an excerpt from Caillois’s Pierres réfléchies (1975)–the last, and least cited, of his books on stones–published for the first time in English. The print essay is complemented by an online exhibit that presents photos of particular specimens of the mineral collection accompanied by Caillois’s speculations about them from The Writing of Stones (1969).

In Rock Records, Caillois’s stone writings are taken up by ecotheorist Jeffrey Jerome Cohen, who perceptively points out that while Caillois discovers in stones a form of cosmic art–thereby liberating art from an anthropomorphic mooring–he simultaneously depicts rock as an inert medium, a “durable recording device” of universal energies and aesthetics. Paul Prudence, a theorist and practitioner of procedural art, begins by pointing out that Caillois, as a pareidoliac interpreting patterns in stone, figures his speculations in terms of the “internalized database of stored images” available to him at the time. He then offers a “post-digital” treatment of Caillois’s writings, seeing them in terms of how they anticipate and/or are changed by viewing them in relation to algorithmic images (fractals, etc), and concludes that an aesthetics of simulation ultimately opens onto a “cybernetics of geology.” Paul A. Harris finds in Caillois’s characterization of stone contemplation as “mental inebriation” and “spiritual exercise” an analogue for his “stoned thinking” grounded in meditative rock gardening practices.

Igneous Ligneous Inosculation: Migmatite

“Migmatite,” meaning “mixed rock,” is a word coined in 1907 by Jakob Johannes Sederholm, for rocks having both igneous and metamorphic properties. Pierre Jardin stumbled on the term on a plaque for a large sinuous-striped, grey and white boulder named “Bob’s Rock” outside the Grassy Hollow Visitors Center on the marvelous Angeles Crest Highway near Wrightwood, California.

As Evelyn Mervine succinctly explains: “Metamorphic rocks are rocks which deform at very high pressures and temperatures and which may recrystallize but which have not formed through melting. Igneous rocks, on the other hand, are rocks which form by cooling from completely molten material.  Migmatites are hybrid rocks: the dark layers (most often composed of biotite and amphibole) experienced metamorphic changes, but did not melt. The light layers (most often granitic in composition; as a reminder, granite consists of the minerals quartz, feldspar, and muscovite), on the other hand, crystallized from partial melts of the precursor rock.”

Pierre Jardin collected pieces of migmatite from an outcropping near Wrightwood. Their heterogeneous composition and pytgmatic foldings make them a natural fit for mixing rocks and wood in compositions Jardin calls “Igneous Ligneous Inosculations” (stones kissing stumps, loosely translated). The undulating folds of the migmatite rock rhyme visually with the sinuous lines of the wood, and the two forms fit neatly, creating nice negative spaces.
